Article Abstract
Biases in the way that people direct their attention towards or away from pain-related information are hypothesised to contribute to the onset and severity of pain-related disorders. This systematic review summarised 24 eye-tracking studies (N = 1424) examining effects of chronic pain, stimulus valence, individual differences in pain-related constructs such as fear of pain and pain catastrophising, and experimentally-induced pain or pain-related threat on attentional processing of visual stimuli. The majority of studies suggest that people with and without chronic pain do not differ in their eye movements on pain-related stimuli, although there is preliminary evidence that gaze biases vary across subtypes of chronic pain and may be evident only for certain stimuli. In contrast, participants with and without chronic pain exhibit a general tendency to allocate more first fixations and total fixations upon pain-related compared to neutral stimuli. Fear of pain was found to have limited effects on eye movements, whereas the tendency to catastrophise about pain, the anticipation of pain, and actual experimental pain stimulation have had stronger associations with eye movements, although results have been mixed. Methodological limitations and future research directions are discussed.

Background: Approximately 69% of Americans with spinal cord injury (SCI) have neuropathic pain. Research suggests that impairments in mental body representations (MBRs; ie, representations of the body in the brain) likely contribute to neuropathic pain. Clinical trials in adults with SCI, focused on restoring MBR, led to improvements in sensation and movement as well as neuropathic pain relief.

Pain Management Unit, Hospital Universitario Quirónsalud Madrid, Madrid, Spain.
Aims: The aim of this observational study is to describe the use of epiduroscopy to decrease the enlargement of the ligamentum flavum (LF) in patients with spinal stenosis, as well as the selection of the appropriate patient and the safety measures that enhance procedural success.
Materials & Methods: We introduce the patient selection protocol, define the appropriate indication and the safety measures to use the epiduroscopy as a tool to decrease the size of the LF and increase space, reducing possible complications.
Results: Among patients included in the study, there were no cases of access difficulty or coccydynia, and one case of urinary incontinence occurred in a patient with Schizas grade D (very severe) stenosis.
Effectiveness of Medical Nutrition Therapy in the Management of Patients with Obesity and Endometriosis: from the Mediterranean Diet To the Ketogenic Diet, Through Supplementation. The Role of the Nutritionist in Clinical Management.
Curr Obes Rep
September 2025
Department of Medicine, Division of Endocrinology, University of Arizona, Tucson, AZ, USA.
Purpose Of The Review: This review aimed to summarize current evidence on the effectiveness of medical nutrition therapy (MNT) in the management of obesity and endometriosis, with a focus on dietary patterns such as the Mediterranean and Ketogenic diets, as well as nutritional supplementation. Additionally, it highlights the central role of the clinical nutritionist in implementing individualized, evidence-based interventions within multidisciplinary care.
Recent Findings: Although the literature reports the existence of an inverse relationship between risk of endometriosis and body mass index, clinical evidence jointly reports that a condition of obesity is associated with greater disease severity.

Introduction: Pharmacological therapies for chronic idiopathic constipation (CIC) are useful, but many patients report dissatisfaction from a lack of efficacy and occurrence of adverse events. The vibrating capsule (VC) is an FDA approved non-pharmacologic, treatment for CIC. However, its long-term usefulness in a community setting is unknown.
